The Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) is a standardized, norm referenced measure of intelligence in which administration and response formats are entirely nonverbal, requiring only universal hand gestures from the examiner and examinee. The UNIT was constructed in order to provide a more appropriate and valid assessment for children who are not fluent in a community’s dominant language and culture. Using multi-sample confirmatory factor analysis, the present study examines standardization for four different racial/ethnic groups (i.e., Whites, Blacks, Asians, and Hispanics), concluding that the observed differences in subtest performance are likely attributable to group differences in factor means. Suggestions for future study are offered.
